Benefits of technology

The present invention has been developed to reduce the size of the second printed circuit board in a liquid crystal display module and device. By integrating a timing controller within the flat flexible cable and providing an enlarged heat dissipating pad on the front and rear faces, as well as the fourth golden fingers on the front and rear faces of the laminated flat flexible cable, the overall size of the flat flexible cable can be reduced while maintaining the same pin counts. This results in a more efficient and compact device design.

Problems solved by technology

Since the TCON takes a majority surface area of the C-board, this is detrimental to the compactization of the C-band.

Embodiment Construction

[0028]A detailed and concise description with respect to each of the following embodiments will be given along with the accompanied drawings. Apparently and it should be noted that the embodiments disclosed hereinafter are merely typical and illustrated one, while should not be construed as whole. It is therefore any alternatives and modifications by the skilled in the art in view of those embodiments should be covered by the appended claims.

[0029]As shown in FIG. 1, the present invention discloses a liquid crystal display module 1, and which includes a first printed circuit board 2, a second printed circuit board 3, and a timing controller 4. The first and second printed circuit boards 2 and 3 are interconnected via a flat flexible cable 5. The timing controller 4 is disposed on the flat flexible cable 5. Accordingly, the timing controller 4 and the flat flexible cable 5 are integral together.

[0030]The first printed circuit board 2 is the X-board within the liquid crystal display m...

Abstract

A liquid crystal display module is disclosed and it includes a first printed circuit board, a second printed circuit board interconnected by a flat flexible cable, and a timing controller encapsulated within the flat flexible cable. The present invention further includes a liquid crystal display module incorporated with such module. The liquid crystal display module and device can incorporate with a second printed circuit board with reduced size, while the heat dissipating effect is increased, and the overall size of the flat flexible cable is reduced.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a technical field of LCD displaying, and more particularly to a LCD module and a LCD device implementing the module.BACKGROUND OF THE INVENTION[0002]Because of the features of low radiation, compact and slim, and low energy exhaustion, the LCD panel has been widely implemented in the fields of mobile phone, personal digital assistance (PDA), notebook computer, and television etc.[0003]In a LCD module, it generally includes a C-board and an X-board interconnected with flat flexible cable. The C-board is generally configured with a timing controller (TCON), and a power module. Since the TCON takes a majority surface area of the C-board, this is detrimental to the compactization of the C-band.SUMMARY OF THE INVENTION[0004]The invention is intended to address the compactization of the C-board in which a TCON is incorporated and which is the key issue hindered the compactization of the C-board.[0005]In order to address the tech...
